In the second part of the series an effective camera zoom is added allowing you to stack the crates higher and higher.

In the second part of Emanuele Feronato's tutorial series he takes the previous prototype and adds new features into it: "Now it’s time to make the game zoom out when you manage to stack crates or soon you will have your moving crate below the highest crate on the stack. Moreover, you won’t be able to see the entire tower you built with crates because it won’t fit on the screen."
